A new study has reawakened the debate over the safety of artificial sweeteners. The findings suggest an association can be detected between sugar substitutes and increased cancer risk, but experts not affiliated with the research question their validity.
-
Exposure to phthalates, a chemical used to manufacture thousands of everyday products, has been linked to an increased risk of childhood cancer. The findings add to research suggesting this chemical may have various deleterious health effects in humans.
-
Manufacturing of chemicals has grown so rapidly that governments are now unable to assess, let alone control the risks to Earth's ecosystems, taking us beyond a safe "planetary boundary" and endangering the planet's stability.
-
An intriguing new study has found a chemical excreted by babies can influence aggression in humans. The findings reveal curious sex-specific responses to the chemical, triggering aggression in women but blocking aggression in men.

A study is offering one of the most comprehensive investigations ever conducted into the origins of cannabis' unique “skunk-like” smell, discovering an entirely new family of sulfur compounds that are chemically similar to compounds found in garlic.
-
A first-of-its-kind study has measured levels of plasticizer chemicals in a number of fast food products. The findings reveal high concentrations of a number of potentially harmful chemicals, such as phthalates, in almost all samples studied.
-
Researchers are calling for urgent action limiting the use of chemicals called phthalates in the production of plastics. A new study estimates up to 100,000 premature deaths in the United States every year could be attributed to phthalate exposure.
